How to make image sequence?
Yes the video will be smooth with the added benefit that you can process each image before creating the video from them.


First you need to create an animation sequence using key frames
By default Blender will save the animation as images, frame by frame after clicking the 'Animation' button as the image bellow. When you give the animation a name, before the clicking the 'Animation' button Blender will number the images in each image name for easy identification.
You can do composition in Blender or you can individually or batch process the images created for the animation, if you desire.
Switching Blender into Video Editing mode you import the images and create the video as in this YouTube tutorial https://www.youtube.com/watch?v=7SNoV-EmDYw&amp;t=2s. The actual video creation starts 1:15 in the tutorial
